KNITTING-MACHINE SPECIFICATION forming part of Letters Patent No. 709,154.,

dated September 16, 1902.

Application filed February 20,1902. Serial No. 94,876. (No model.)

To all whmn it may concern.-

Be it known that I, HENRY JANSSEN, a 0111- I zen of the United States of America, and a resident of Reading, in the county of Berks and State of Pennsylvania, have invented certain new and usefullmprovements in Knitting-Machines, of which the following is a specification.

My invention relates particularly to full- :fashioned hosiery-machines of the cotton type arranged to knit a series of stockings simultaneously; and it consists in certain improved mechanism designed for use in conthe novel features are specifically pointed out in the claims.

Figure 1 is a partial sectional elevation of a knitting-machine of the class referred to, indicating only so much thereof as is necessary to the understanding of my improved mechanism, which is shown applied thereto in preferred form. Fig. 2 is a fragmentary front elevation of a portion of the narrowing mechanism. Fig. 3is a plan or edge view of one of the operating-levers forming part of my improved mechanism. Fig. 4 is a fragmentary view of a stocking, showing the diamond-point feature which isproduced by the narrowing mechanism to which my improvements are adapted.

As already stated, the general construction and operation of the machine are wellknown and need not be shown or described, except so far as relates to the movements to be effected by means of my improvements. The needles 1 are carried and moved and the threads are led thereto as usual. The narrowing or fashioning points 2, which are employed to pick loops from certain of the needles in the narrowing operation,are also carried, as usual, by parallel longitudinal rods 3, to which lengthwise movements are given to bring the fashioning-points to proper position with respect to the needles, and said rods 3 are guided in brackets 4, carried by the narrowing-mechanism arms 5 on shaft 6, so as to be swung up and down by the turning of the latter, as indicated by the dotted position of-said arms 5 shown in Fig. 1. The whole narrowing mechanism is normally carried above the needles and lowered at intervals to cooperate therewith, as required, by means ordinarily employed, but not shown, as forming no part of the present invention. This bracket 4 has an arm 7, in which is rotatably mounted a shaft 8, extending lengthwise of the machine and provided at intervals with guard-arms 9, fixed thereto and carrying guardblades 10. These guards when swung toward the fashioning-points 2 are adapted to press against certain of the latter, so as to prevent them from engaging with the corresponding needles, thus preventing the picking of the loops from such needles in the operation of footing and pro-- viding for the production of what is termed the diamond point in the toe of the stocking, as indicated in Fig. 4.

The mechanism and operation above referred to form no part of my present invention, which relates to the improved mechanism for effecting the required movements of the narrowing mechanism, which I will now describe, as shown in the drawings.

The movement of the guards 10 into and out of contact position with the fashioningpoints 2 requires to be effected automatically during the operation of the machine and is effected by means of a lover or levers 11 and connected mechanism as follows: The lever 11 is pivoted at one end to a shaft 12 and is provided intermediate of its length with a suitably-mounted roller 13, which bears nor" mally upon the concentric periphery 14 of a disk fixed to the rotary shaft 15,11pon which the lever is thus supported without movement; but when said shaft 15 is moved longitudinally at predetermined intervals the bearing of said roller 13 is transferred from the concentric periphery 1a of said disk to an eccentric periphery 16, which raises the pivoted lever 11. Pivotally connected to the free end of the lever 11 is a rod 17, the upper end 18 of which is slidably engaged in a sleeve 20, which in turn is pivotally connected at 21 to an arm 22, fixed to the shaft 8. The free movement of the rod end 18 in said sleeve is limited by a shoulder or stop 19, which comes in contact with said sleeve before the lever 11 is fully raised and raises it, so as to turn the shaft 6 and swing the guards 1O outward, as indicated by the dotted lines. When the lever 11 is lowered, the guards are normally pressed toward the fashioning-points 2 by means of a spring or weight. (Not shown.) The movement of the pivoted sleeve from its normal position in swinging the guards 1O outward is indicated by dotted lines. intermittent movement of the guards 10, it will be seen, is elfected automatically by means of the mechanism just described without interfering with the movement of the narrowing mechanism as a whole by the swinging of the arms 5 on the shaft 6, as indicated by the dotted lines already referred to. It may be desirable to make this upward movement of the whole narrowing mechanism during the operation of the machine in order to permit of convenient access to the parts, yet the mechanism should be rigidly held in raised position when it is moved thereto and there should be no disconnection of the mechanism already described for operating the guards 10. To conveniently effect this raising and lowering of the whole narrowing mechanism and provide for rigidly holding the same, I employ a lever 34, fixed to the shaft 12 and pivotally connected at pivot 35 near its free end to a rod 23, which in turn is pivotally attached at its upper end to the shaft 24 of the narrowing mechanism, in connection with a hand mechanism for operating said lever 21, comprising a bell-crank 25 26, loosely mounted on the shaft 12 and having its short arm connected by a pivoted rod 27 to an arm 28 on shaft 29, the turning of which latter by the swinging of the bell-crank arm 26 upward to its dotted position against the stop 30 causes the end 31 of arm 32 on shaft 29 to swing forward to its dotted position indicated, thus raising the outer end of lever 21, together with the connected narrowing mechanism. In raising the bell-crank lever 26 to effect this movement the short arm 25 thereof is swung outward to the dotted position indicated, slightly beyond the dead-center point This sired to lower the same again into position v for carrying on the normal operation of the machine.

The preferred construction shown may evidently be modified without departing from the spirit of the invention.

What I claim is 1. In a knitting-machine the combination with the movable narrowing mechanism and the lever carried thereby, of the swinging arm arranged to engage and raise said lever and narrowing mechanism, and the handlever having an arm connected to said swinging arm and a limited movement arranged to carry the point of connection slightly over the dead-center to lock said swinging arm in its elevating position, substantially asset forth.

2. In a knitting-machine the combination with the movable narrowing mechanism comprising adjustable points and pivoted guards arranged to contact with said points, of an independent hand-lever mechanism for elevating said narrowing mechanism and an automatic operating mechanism for said guards comprising a device connected to said pivoted guards, an operating-rod therefor having a limited sliding movement in said device, and a lever-and-cam connection to said rod adapted to intermittently raise said device to withdraw the guards from the narrowing-points, substantially as set forth.

3. In a knitting-machine the combination with the movable narrowing mechanism comprising adjustable narrowing-points and pivoted guards arranged to contact with said points, of an automatic operating mechanism for said guards comprising a device pivotally connected to said pivoted guards, a rod having a limited slidingmovement in said device, and a lever-and-cam connection to said rod adapted to intermittently raise said device and thereby withdraw the guards from the narrowing-points substantially as set forth.

Signed at Reading, Pennsylvania, this 12th day of February, 1902.
